We followed the contour of the snowbound crater of Mount St. Helens.

What do Mount Etna, Mount St. Helens, and Saint Peter and Saint Paul Rocks (wait, what's this last one?) all have in common? While the first two are volcanoes, and the third an isolated and strikingly rugged outcrop in the middle of the Atlantic Ocean, they are all grandiose natural phenomena that we managed to scale by either air, land, and sea.

Many years ago we sailed from Brazil to St. Peter and St. Paul Rocks, 15 very tiny rocky outcroppings that lie smack dab in the middle of the Atlantic Ocean, halfway between Africa and South America. They practically sit on the equator, at just slightly over 60 miles north of the line. A needle in a haystack in the grand scheme of the vast Atlantic Ocean, this archipelago is extremely tiny, with its highest point only about 60 ft. above sea level. St. Peter and St. Paul Rocks belong to Brazil and are the exposed jagged pinnacles of an underwater mountain ridge or the “abyssal mantle," that plunges 4000 meters deep into the ocean.

We anchored at the mouth of the bay's guardian pinnacles, and it was like sitting on top of the world. It must have been the closest landscape on earth to resemble what we would imagine the Moon to be. Not a speck of green—no vegetation whatsoever—was to be seen. Course, dark, lava crags jutted out everywhere, strangely coiffed with snowy caps—deep and widespread layers of guano. Birds of all types just swarmed around the Rocks, while the bay was said to be chock-full of sharks. Hoping that the sharks weren’t as numerous as rumors held, we maintained a safe distance anyway: no swimming in this bay.

Landing with the dinghy to explore this savage shore was a tricky dance of fancy footwork, trying to gain sturdy footholds in the rock face that we tied up to while negotiating a heaving swell. Once we thrust ourselves over the rocky ledge, we were surrounded by an eerie and breathtaking landscape of a wide rocky plateau, dotted with innumerable tidal pools. The plateau bristled with a gleaming carpet of peculiar one-armed crabs, winding around and around waving their single “menacing” claws (which were quite cute). Flying fish that had flown too high dotted the rocks. Spectacular and noisy waves crashed over the cliffs, rocks, and pinnacles, and our view of the landscape from our anchored boat was confirmed: there was no vegetation whatsoever.

Numerous and aggressive, the bird population lived up to their reputation as they attempted to overpower and threaten us. They had no fear of humans, since they rarely had contact with such a beast. They would rush, dive-bomb, and cackle, and those with their young in nests, were more acutely aggressive. After a while, we all seemed to reach an acceptable truce as a certain invisible barrier was established. One step beyond that frontier, and off they re-launched into attack mode.

Years later we marveled from aloft with a 360° view of Mount St. Helens, Washington, while nestled in a small private plane circling the rim of the volcano. It was a rare crystalline Pacific Northwest winter day in January, devoid of a single cloud. Taking off from Hood River, Oregon our pilot flew due west and we were immediately surrounded by an unparalleled panoramic view of multiple majestic volcanic white sentinels that jutted up from the Earth's floor. Behind us Mount Hood and Mount Adams flanked the Columbia River Gorge, Mount Jefferson reigned in the distant southeast, and Mount St. Helens loomed smack dab in the center of our windshield like a bulls-eye. Mount Rainier shadowed Mount St. Helens in the near background.

As we followed the contour of the snowbound crater of Mount St. Helens, we were starkly reminded that it was still vitally active. A distinct plume of smoke wafted from the bottom of its hollowed-out center, like steaming gravy rising up from the dimple of a scooped out mound of mashed potatoes. A log-jammed lake on the volcano's flank was all that was left of a forest toppled and frozen in time since the 1980 explosion. The crispness of the day, of the sparkling snow, the shifting peaks at our eye level made it feel like we were in in a life-sized 3D diorama, or a National Geographic film extravaganza spilling from an Imax screen.

Recently we ventured to Mount Etna in Sicily—an entirely different active volcano experience. About an hour's drive outside the seaport of Catania and all its cacophony, our ascent to Mount Etna was a pleasant drive via a gradual uphill grade through villages on back country roads. The richly-colored earthen and multi-mineral hued nuanced folds of the crater's skirt cascaded softly down to the staging and cable car landing area at Rifugio Sapienza where we parked our rental car. Although this late Sicilian September day was 80 degree-plus, we easily donned jackets once we alighted here. We boarded the cable car and slid up the mountain to the waiting monster passenger four-wheel drive "truck buses" for the last few miles to the top, and a closer view of the mountain. Bobbing inside these massive oversized vehicles, we zig-zagged up the winding switchbacks to a plateau at nearly 10,000 ft. where Mount Etna loomed above our heads poking in and out of undulating wispy feathered clouds.

Unlike Mount St. Helens and other volcano profiles, much of Mount Etna's surrounding terrain wasn't jagged and rugged but exuded a soft and cozy yet eerie eminence. Like huge mounds of freshly ground coffee, or heaps of just-dumped enriched garden potting soil, this mountain beckoned us to plunge our arms elbow deep down into its velvety-looking earth. Walking along a ridge, we skirted occasional plumes of smoke that wafted out of this "fertilizer." We could feel the warmth on our hands as we laid them on the ground in those spots.

From Rifugio Sapienza, one can also hike two hours up to the top, but we were intrigued to ride in one of these monster trucks so we opted, instead, to walk back down and sink our feet into the supple dirt. On March 16, 2017, just six months after our visit, this largest active volcano in Europe erupted.

We all hear the many voices that tell us to "Just go," and "Pull off those blinders; see the world." Alas, it's not always that easy. When we get out of our own way we can truly see how small we are, and how expansive the Earth is. There are so many ways to get to the tops—and there are so many of them—all around us. We were on them, over them, and through them. Even just a day hike can take you there—spot on.

My husband was an architect, and then he wasn’t. I was supposed to become a famous journalist, but I didn't. Our choice to live and sail on a sailboat with our two children for 10 years had us hopscotching and dancing around our careers during that chunk of time....Could we, should we, have expected more of our two boys?
